This invention appertains to strainers for showing my improved deviceincorporated drain pipes and has for one of its primary therein, partsof the device and drain pipe objects to provide means for incorporatinga being broken away and in" section; removable strainer with a drainpipe for a Figure 2 is a vertical section taken on the sink or the likeadjacent to or forming a part line 22 of Figure 1 looking in thedirec-"sa' of the trap thereof so as to preclude the ention of thearrows showing my improved trance of debris into the trap and theconsestrainer tray mounted within the casing; quent clogging up thereof,the strainer being Figure 3 is a horizontal section taken on freelyremovable from the trap by the ordithe line 33 of Figure 1 looking inthe dil0 nary layman. rection of the arrows, and 60 Another importantobject of my invention v Figure A is a detail perspective view of is theprovision of a sliding tray incorporated the strainer tray. with a drainpipe at the trap portion thereof, Referring to the drawings in detail,wherethe tray being provided with a reticulated in similar referencecharacters designate lower wall extending transverselyacross thecorresponding parts throughout the several 05 pipe for permitting thefree flow of water views, the letter A generally indicates atherethrough, but holding all solid matter strainer pipe for a sink Bincluding the usual therein with novel means for permitting the U-shapedtrap 5', and O my improved device quick removal of the tray from thetrap or incorporated with the strainer pipeA within pipe for cleaningpurposes. the length thereof between the sink B and IO A further salientobject of my invention the trap 5.

A still further object of my invention is to and these ribs are locatedat a point equiprovide an improved strainer for drain pipes distant ofthe upper and lower portions of of the above character, which will bedursaid casing. I

"* able and efficient in use, one that will be In conjunction w1th thecasinglemploy the en simple and easy to manufacture, and one removabletray 20 which can-be formed of which can be placed upon the market at asheet metal. This tray 20 includes longitudireasonable cost..nallyextending side walls 21, an arouate rear With these and otherobjects in view, the wall 22, a flat bottom wall 23 and a front wallinvention consists in the novel construction, 24. The front wall2l'extends below the bot- J5 arrangement and formation of parts, as willtom wall 23 and the sidewalls 21, so as to 0011- I be hereinafter morespecifically described, stitute a finger grip to facilitate the placingclaimed, and illustrated in the accompanying of the tray in position andthis walllalso exdrawings, which drawings tends beyond the side walls.The upper edges Figure 1 is a side elevation of a drain pipe of the sidewalls 21 and the rear wall 22 are 1 0 provided with laterally extendingflanges 25 and the flanges of the side walls are adapted to rest on theguide and supporting ribs 15 formed on the casing 10. The flange formedon the rear wall 22 is adapted to abut against the integral rear wall 12of the casing so as to preclude the passing of solid matter between thesame and the rear wall of the casing.

The front end of the tray when in position Within the casing extendsslightly beyond the front edge of the casing and is adapted to beengaged by the screw cap 13 which cap urges the same into the casing tobring the flange on the rear wall thereof into intimate contact with therear wall 12 of the casing, thereby positively locking the tray inposition against accidental turning movement.

The lower wall of the tray can be formed of reticulated material and inthe present instance I have shown the bottom wall thereof provided witha plurality of drain openings 26.

Then the tray is in position in the casing 10 shown in Figures 1 and 2of the draw ings, it can be seen that the same completely extends acrossthe drain pipe and thus all .water draining from the sink will of necessity pass through the tray and into the trap 5. The apertures 26 willpermit the free pas sage of water through the tray, but will positivelyhold all foreign matter back from the trap and in the tray. By thisconstruction the clogging up of the trap is prevented and all debris canbe easily and quickly removed from the drain pipe.

W'hen it is desiredto remove the strainer tray for cleaning purposes, itis merely necessary to grasp the handle 14 and unthread the cap 13 fromthe side wall of the casing, after which the fingers grasp the frontwall. 24 of the tray and the tray is removed. The debris Within the traycan now be dumped out of the same and the tray cleaned and then replacedin position in the pipe. After the tray has been inserted, the cap canagain be threaded into position, which as stated holds the tray inplace.

From the foregoing description, it canbe i seen that I have provided aneffective and simple device for preventing the clogging up of a drainpipe and for permitting the effective and easy cleaning thereof.

Changes in details may be made Without departing from the spirit or thescope of this invention, but:

lVhat I claim asnew is:

In a drain including a pipe having a trap 1 and a casing extendingdiametrically through the pipe above the trap and projecting beyond theopposite sides thereof, having a cylindrical side wall and a rear wall,longitudinal ribs on theinner face of the side wall above the trap, aremovable cover threaded on the. front of the casing; a removable traywall engaging the inner face of the removable cover, the side edges ofthe bottom wall engaging the inner faces of the side wall of the casingat a point below said ribs, as and for the purpose specified.

In testimony whereof I afiixmy signature.

ANGEL IZQUIERDO.
